Kubernetes(3:部署)

1 3个节点：
k8s-master k8s-node1 k8s-node2
2
yum install -y docker
3
所有节点安装kubelet kubeadm kubectl
4 master执行：105为MASTER的IP，网络方案是flannel
kubeadm init --apiserver-advertise-address 192.168.56.105 --pod-network-cidr=l0.244.0.0/16
5 master配置kubectl，不要用root用户
su - ubuntu
mdkir -p xx/.kube
sudo cp -i /etc/kubernetes/admin.conf xx/.kube/config
sudo chown ubuntu:root xx/.kube/config
echo "source <(kubectl completion bash)" >>~/.bashrc
6 master安装pod网络(使用flannel)
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
7 查看token: kubeadm token list
8 两台node注册到master
kubeadm join --token xxxxxx masterip:6443
9Master上查看node
kubectl get nodes

10 查看所有pod的状态
kubectl get pod --all-namespaces
